Qwen 2.5 72B Instruct on the Apple M3 Max: VRAM by quantization

Quant	VRAM needed	Fits 64 GB?	Max context
F16	146.1 GB	✗ No	—
Q8_0	78.6 GB	✗ No	—
Q6_K	61.2 GB	✓ Yes	8K
Q5_K_M	53.2 GB	✓ Yes	32K
Q4_K_M	45.6 GB	✓ Yes	32K
Q3_K_M	32.8 GB	✓ Yes	64K
Q2_K	25.8 GB	✓ Yes	64K

VRAM needed assumes a 4K-token context with an f16 KV cache; “Max context” is the largest window that still fits in 64 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
